But he never made the flight and has not been heard from since.
Today, police shared that Carter was at the airport for an hour and a half before he left in a taxi about 2.10pm and travelled to Trigg Beach.
He arrived about 30 minutes later and was last seen near a surf club on West Coast Drive, which stretches from South Trigg to Sorrento.
He was carrying a small backpack and wearing a black t-shirt, shorts and black and white sneakers at the time.
His family and police have serious concerns about his welfare, and anyone with information on his whereabouts is urged to immediately contact 131 444.
Carter is described as being about 174cm tall with a slim build, brown hair and blue eyes.
